Matthew Joseph, a 23-year-old suspected of homicide and armed robbery, shot Hill in the head and shot a Detroit police sergeant in the leg near the corner of Linwood and Hooker on April 2, police said. Officers returned fire, killing Joseph.

The incident started when officers stopped Joseph’s car on the city’s west side. Joseph opened his car door and began firing, police said at the time.

The officers were part of the Comprehensive Violence Reduction Partnership unit, a partnership among the Detroit police, the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives, the Michigan State Police, the Wayne County Sheriff’s Office and the Michigan Department of Corrections.

Joseph, who was convicted on armed robbery and weapons charges in 2007, was released from prison on parole in October 2012. He was being sought in connection with a March 28 homicide at a Detroit motel, the Free Press reported in April.
